[pca] patch precedence between 121430-57 and 121428-LR

[Gerard Henry]

hello all,
i'm tryng to install prerequisites patches before liveupgrade a S10u8 
machine.
The oracle doc ID 1004881.1 recommends: "Apply the patches in the order 
in which they are listed to the system's PBE" and the list is:
119254-LR  Install and Patch Utilities Patch
121430-57  Live Upgrade patch
121428-LR  SUNWluzone required patches

but with pca, the order is changed as followed:
fury-root% /etc/scripts/pca -r 121430-57 121428
Using /var/tmp/patchdiag.xref from Aug/22/11
Downloading README for 121428-15
Trying http://www2/cgi-bin/pca-proxy.cgi?
Done
Downloading README for 121430-57
Trying http://www2/cgi-bin/pca-proxy.cgi?
Done

i notice that patch 121428-15 seems to contain only one file:
/etc/lib/lu/plugins/lupi_zones

so perhaps, the order isn't very important in this case. But does 
anybody else have seen this kind of problem ?

thanks in advance for help,

gerard
